IMPROVEMENT IN COOKING-STOVES.

Specification forming part of Letters Patent No. 145,26, dated December9, 1873; application filed May 29, 1873.

To all whom it may concern:

Be it known that I, LEwIs E. CLow, of St. Louis, Missouri, have inventedan Improved Combination-Stove, of which the following is a specication:

This invention is a parlor-stove, which is also adapted for cookingpurposes, and in which either coal or wood may be used. Its noveltyconsists in the construction and arrangement of its various parts, aswill be fully described hereinafter.

0f the drawing, Figure 1 is a longitudinal sectional elevation 5 Fig. 2,a front elevation. Fig. 3 is a rear elevation; Fig. 4, a top plan, withpart of corners broken away.

A represents an ordinary parlor wood-stove, having the usual front,bottom, and back lining to form the return-flue a. The chamber or ilue acorresponds to the outline of the stove A, surrounding the front,bottom, and back portions of the same. B, Fig. 4, is a rotary grate. Inline with grate B, I provide the iireplace with surrounding side and endbearingplates b, which support the surrounding side and end linings B.linings B' can be made detachable, to admit of (See Figs. 1 and 4.) Thetheir removal when the stove A is used for wood only, if desired,although with linings B' either wood or coal may be used. I also providethe stove A, near the top of its iiue a, with a cold-air duct or pipe,G. The pipe C extends from side to side, and has perforations By meansof the pipe C, a more perfect utilization and combustion of heated gasesis obtained before the same D is an ash-pit with ash-box. D is thehearth communicating with ash-pit. The draft is obtained through ahearth-plate, d, properly formed to close the open tops of the hearthD', as well as the vertical opening in front of the ustove A, (see Figs.1, 2, and 4,) and also through the side or front lining B', which, forthis purpose, has one or more openings, d1. (See Fig. 1.) d2, Figs. 1,2, and 4, are sliding doors.

The top of the stove is hinged, and may be thrown back for the removalof the linings B', charging the fire with large wood, or other purposes.

a2 represents the direct ue, which is controlled by the two-way dampera3. When this damper is open, the gases pass directly into flue F, andfrom thence into the chimney. When the damper is closed, the heatedgases, 85e., must then pass through circuit-flue a, and out of same. M

To give the stove A a further combined character, the back of the same,as shown in Fig. 1, has attached thereto a cooking-stove, consisting ofthe oven E, and surrounding the same the ue c, which is but acontinuation ofthe flue a of the parlorstove, that of the ue a beingclosed by plates e1 and c2. The circuit thus formed will be as indicatedwith arrows-that is, if damper a3 is closed, as shown in Fig. l. The topplate of the oven has the usual pot-holes. F is an extension.- lue,which extends from side to side of the stove, Figs. 3 and 4, and so asto communicate with the entire width of flue c. Said extension F isformed so as to meet and make proper connection by a cap with stove-pipeand chimney.

The flue, it will be observed, is constructed below, so as not tointerfere with the pot-holes of the part E, and expanded above, to givea large surface for the radiation of heat.

The flues a and c are readily cleaned by openings left in the side andrear of stove.

I am aware of the patent No. 87,688, and do not, broadly, claim carryinga ilue above the upper surface of the stove; but

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The stove described, having the central portion A, with fire-box Band flue a, extending about the front and bottom of the part A, and alsobottom, rear, side, and top of oven E, the two-way damper a3, and theextension-flue F, constructed and arranged as described, for the purposeset forth.

2. The flue F, extending above the top plate of part E, and constructedwith a contracted portion below, for the purpose of leavin g space forthe pot-holes, and a gradually-expanding top above, to give increasedsurface for the radiation of heat, in combination with the flues c a2and two-way damper a3, as described.

In testimony of said invention I have hereunto set my hand.
